The patch titled
Subject: vmalloc: make find_vm_area check in range
has been removed from the -mm tree. Its filename was
vmalloc-make-find_vm_area-check-in-range.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: HATAYAMA Daisuke <d.hatayama@xxxxxxxxxxxxxx>
Subject: vmalloc: make find_vm_area check in range
Currently, __find_vmap_area searches for the kernel VM area starting at a
given address. This patch changes this behavior so that it searches for
the kernel VM area to which the address belongs. This change is needed by
remap_vmalloc_range_partial to be introduced in later patch that receives
any position of kernel VM area as target address.
This patch changes the condition (addr > va->va_start) to the equivalent
(addr >= va->va_end) by taking advantage of the fact that each kernel VM
area is non-overlapping.
